JZL-D type natural rubber tensile testing machineInstrument usage:
Natural rubber tensile testing machineIt is a tensile strength testing machine used to measure the tensile strength and elongation at break of non-metallic materials such as rubber, plastic, and film. The testing machine is a double screw vertical structure, and its structural parameters and technical performance are developed based on the relevant provisions of national standards such as GB/T453-2002 "Determination of Tensile Strength of Paper and Paper Pattern Plates (Constant Speed Loading Method)", GB13022-91 "Test Method for Tensile Properties of Plastic Films", GB/T8808-1988 "Peel Test Method for Soft Composite Plastic Materials", GB/T1130-1991 "Test Method for Right Angle Tearing Performance of Plastics", and GB/T12358-1998 "Test Method for Thermal Strength of Plastic Film Packaging Bags" for tensile performance testing of non-metallic materials. The upper and lower fixtures are connected by universal joints to ensure the concentricity of the clamping, which can evenly distribute the force on each part of the sample and display the test results more realistically. The sample clamping is convenient, firm and durable. Applied computer measurement and control technology, the display screen displays test data such as force values, elongation, and stress-strain; Equipped with overload protection, limit protection, peak holding, and automatic return to initial position after sample breakage, with a stretching speed of 1-500mm/min according to standard requirements; Selecting different testing methods based on different samples corresponds to different testing speeds; Inkjet printers print test reports with curves, which are fully functional, structurally simple, and easy to operate and maintain. This product is an essential testing instrument for quality inspection departments at all levels, colleges and universities, and small and medium-sized non-metallic material production units.

IIInaturalAdhesive tensile testing machineSystem composition and working principle, testable items

3.1 The system consists of three parts: the host, the electrical control system, and the digital control system.
3.2 Working principle
3.2.1 Mechanical Transmission Principle
3.4 Common Test Items: (Common Display Values and Calculated Values)
● Tensile stress ● Tensile strength
● Tensile strength ● Tensile elongation
● Constant tensile stress ● Constant elongation at constant stress
● Fixed stress value ● Tear strength
● Force value at any point ● Elongation at any point
● Extraction force ● Adhesive force and peak calculation value

The main unit of Jiangdu Jingzhuo tensile machine consists of a motor and controller, ball screw, guide column, moving crossbeam, limit device, etc. The mechanical transmission sequence is as follows:
Motor - Synchronous belt pulley - Screw - Test bench
4.2.2 Force measurement system: A tension sensor is installed on the moving crossbeam of the host, and the lower end of the sensor is connected to the upper clamp. During the test, the force on the sample is converted into an electrical signal through the force sensor and input to the microcomputer acquisition and control system.
4.2.3 Extension automatic tracking device: This device is used to measure the deformation of the sample. It is held by two tracking clamps with extremely low resistance on the sample. As the sample is subjected to tension, it deforms, and the distance between the two tracking clamps increases accordingly. The tracking clamp converts linear motion into rotational motion through a wire rope and pulley, and inputs the displacement into an electrical signal into a microcomputer acquisition and control system through a tracking encoder.
4.3 Limit protection devices and fixtures
4.3.1 Limit protection device
The limit protection device is an important component of this machine. The host is fixed with a limit rod, which is equipped with two adjustable retaining rings. During the test, when the stopper and the retaining ring touch, it will drive the limit rod to move, making the limit device
Cut off the path in that direction, and the host will stop running. At this point, run in the opposite direction, and the testing machine can work normally. By adjusting the position of the retaining ring on the limit rod, the travel of the moving crossbeam can be limited, providing great convenience and safe and reliable protection for conducting experiments.

VInaturalAdhesive tensile testing machineThe use and operation of instruments

6.1 Firstly, check and confirm that the plug-in cables of the testing machine host and microcomputer control system are connected correctly.
6.2 When the main power supply of the rotating pop-up testing machine ("emergency stop" button) needs to be stopped or shut down urgently, press the "emergency stop" button. Turn on the power supply of the microcomputer control system.
7naturalAdhesive tensile testing machineAttachment

7.3 One copy of specialized testing software for tensile testing machine.
7.4 One set of branded computer and one color printer
7naturalAdhesive tensile testing machinePrecautions
7.1 Before starting up, it is necessary to check whether the connection wires, plugs, sockets, and power plugs and sockets between the CNC system and the host are correct or loose. Only after confirming that they are correct can the system be turned on (for example, if the grounding wire under the power socket in the CNC system controller is loose, it will cause the host to lose control). Please remember the startup sequence, first turn on the power supply of the testing machine host, and then turn on the power supply of the CNC system. When shutting down, first turn off the power supply of the testing machine host, and then turn off the power supply of the CNC system. After turning on, do not plug in or unplug any plug.
The inspection of the position of the upper and lower limit retaining rings is very important. It is necessary to maintain a certain distance between the two fixtures to avoid damage to the components, especially the sensors, caused by misoperation or loss of control of the host.
During the experiment, please do not press the keys on the microcomputer control system.
7.4 Select fixtures according to the specific conditions of the experiment to avoid damaging the fixtures.
7.5 Sudden power outage, please immediately turn off all power sources and wait for confirmation of stable power supply before turning on in sequence. Frequent interruptions in the power supply can easily damage the microcomputer control system and motor speed regulation system.
During the operation of the host, test personnel should not stay away from the machine.
The input tensile speed value of 7.7 must be equal to the actual tensile speed of the testing machine, especially in tearing and peeling.
7.8 When the fracture force value of the specimen is unclear, tensile testing should not be performed, otherwise the sensor may be damaged due to overload.
